BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an electronic device including a touchscreen display and an interface method using the same and, moreparticularly, to an electronic device including a touch screen displayand an interface method using the same that perform operationsassociated with a detected touch, when a touch is detected.

2. Discussion of the Related Art

Recently, the display technology depicting and displaying 3-dimensional(3D) images is being extensively researched and developed and applied ina variety of fields. Most particularly, electronic devices applying thetechnology of displaying 3D images so as to display 3D images, haverecently been drawing a great deal of attention.

The technology of displaying 3D images refers to a display technologyusing a parallax (or difference) in stereoscopic perspectives enabling aviewer to volumetrically view (or see) the displayed image due to theparallax (or difference) in both perspectives. Herein, the 3D displaytechnology may be categorized into a shutter glass display method, anon-glasses display method, a real 3D display method, and so on. Morespecifically, the shutter glass display method is disadvantageous inthat the viewer is required to be equipped with a separate device, suchas putting on a separate pair of polarized 3D glasses. And, thenon-glasses display method is disadvantageous in that the viewer canview the displayed 3D images only at a specified location. Accordingly,since diverse disadvantages exist in the shutter glass display methodand the non-glasses display method, extensive development of the real 3Ddisplay method is currently in progress.

Additionally, the recent electronic devices are being developed to havea slimmer structure in order to enable the users (or viewers) tore-position (or re-locate) their display devices with more convenience,and the recent electronic devices are being developed so as to beequipped with an input device, such as a touch pad or a touch screen,for a more convenient manipulation of the electronic device. In therecently developed electronic devices, when the touch pad or the touchscreen is touched, the respective operations may be performed. Herein,such operations may correspond to selecting particular items from thedisplay screen. Furthermore, such operations may include paging (i.e.,turning pages), scrolling, panning, zooming, and so on.

In the touch pad, the motion of an input pointer corresponds to arespective movement of the user's finger, when the user's finger moves(or slides) along the surface of the touch screen. Conversely, a touchscreen corresponds to a type of display screen having a touch-sensitivetransparent panel covering the display screen. When using the touchscreen, (generally by using a stylus pen or his (or her) finger) theuser directly points to a graphic user interface (GUI) object from thedisplay screen, thereby selecting the corresponding GUI object.

DETAILED DESCRIPTION OF THE INVENTION

Reference will now be made in detail to the preferred embodiments of thepresent invention, examples of which are illustrated in the accompanyingdrawings. Wherever possible, the same reference numbers will be usedthroughout the drawings to refer to the same or like parts.

In addition, although the terms used in the present invention areselected from generally known and used terms, some of the termsmentioned in the description of the present invention have been selectedby the applicant at his or her discretion, the detailed meanings ofwhich are described in relevant parts of the description set forthherein. Furthermore, it is required that the present invention isunderstood, not simply by the actual terms used but by the meanings ofeach term lying within.

FIG. 1 illustrates a block view showing a structure of an electronicdevice according to an embodiment of the present invention.

Referring to FIG. 1, the electronic device 100 according to the presentinvention includes a tuner 110, demodulator 120, a network interface130, a signal processor 140, a display 150, an audio output unit 160, aninput device 170, a storage 180, and a controller 190. Herein, theelectronic device 100 may correspond to a personal computer system, suchas a desktop computer, a laptop computer, a tablet computer, a handheldcomputer, and so on. Additionally, the electronic device 100 may alsocorresponds to a portable device, such as a mobile phone, a smart phone,a digital broadcasting equipment (or terminal), a personal digitalassistant (PDA), a portable multimedia player (PMP), a navigationsystem, and so on, or may correspond to a fixed electronic householdappliance, such as a digital television (DTV) receiver.

Among a plurality of radio frequency (RF) broadcast signals beingreceived through an antenna, the tuner 110 selects an RF broadcastsignal respective to a channel selected by the user (or viewer). Then,the tuner 110 converts the selected RF broadcast signal to anintermediate frequency (IF) signal or a baseband video or audio signal.For example, if the selected RS broadcast signal corresponds to adigital broadcast signal, the tuner 110 converts the selected signal toa digital IF (DIF) signal. And, if the selected RF broadcast signalcorresponds to an analog signal, the tuner 110 converts the selectedsignal to an analog baseband video or audio signal (CVBS SIF). Morespecifically, the tuner 110 may process digital broadcast signals oranalog broadcast signals. The analog baseband video or audio signal(CVBS SIF) outputted from the tuner 110 may be directly inputted to thesignal processor 140.

Furthermore, the tuner 110 may also receive single-carrier RF broadcastsignals according to an advanced television system committee (ATSC)method or multi-carrier RF broadcast signals according to a digitalvideo broadcasting (DVB) method.

According to another embodiment of the present invention, the electronicdevice 100 may be provided (or equipped) with at least 2 tuners. Whenthe electronic device 100 is provided with at least 2 tuners, just as afirst tuner, a second tuner selects an RF broadcast signal respective toa channel selected by the user (or viewer), among a plurality of radiofrequency (RF) broadcast signals being received through an antenna, thetuner 110. Then, the second tuner converts the selected RF broadcastsignal to an intermediate frequency (IF) signal or a baseband video oraudio signal.

Additionally, among the received RF broadcast signals, the second tunermay sequentially select TS broadcast signals of all broadcast channelsstored through a channel memory function, thereby converting thesequentially selected RF broadcast signals to intermediate frequency(IF) singles or baseband video or audio signals. The second tuner mayperiodically perform the conversion procedures of all broadcastchannels. Accordingly, the electronic device 100 may display the imageof the broadcast signal converted by the first tuner and maysimultaneously provide images of broadcast signals respective to severalbroadcast channels converted by the second tuner in the form ofthumbnail views. In this case, the first tuner converts the main RFbroadcast signal selected by the user to an IF signal or a basebandvideo or audio signal. And, the second tuner may sequentially and/orperiodically select all of the RF broadcast signals, with the exceptionfor the main RF broadcast signal, thereby converting the sequentiallyand/or periodically selected signal to an IF signal or a baseband videoor audio signal.

The demodulator 120 receives the digital IF (DIF) signal converted bythe tuner 110 so as to perform the demodulation procedure. For example,in case the digital IF signal outputted from the tuner 110 correspondsto an ATSC type signal, the demodulator 120 performs an 8-vestigial sideband (8-VSB) demodulation procedure. In another example, if the signaloutputted from the tuner 110 corresponds to a DVB type signal, thedemodulator 120 performs a coded orthogonal frequency divisionmodulation (COFDMA) procedure.

Moreover, the demodulator 120 may also perform channel-decoding. Inorder to do so, the demodulator 120 may be provided with a trellisdecoder, a deinterleaver, a Reed-Solomon (RS) decoder, and so on, so asto perform trellis decoding, deinterleaving, and Reed-Solomon (RS)decoding.

After performing the demodulation and channel-decoding processes, thedemodulator 120 may output a stream signal (TS). At this point, thestream signal may correspond to a multiplexed signal having a videosignal, an audio signal, or a data signal multiplexed therein. Forexample, the stream signal may correspond to an MPEG-2 transport stream(TS) consisting of an MPEG-2 standard video signal multiplexed with aDolby AC-3 standard audio signal multiplexed. More specifically, theMPEG-2 TS may include a 4-byte header and a 184-byte payload.

The stream signal outputted from the demodulator 120 may be inputted tothe signal processor 140. The signal processor 140 performsdemultiplexing and signal processing procedures on the inputted streamsignal. Thereafter, the signal processor 140 outputs the video data (orvideo signal or image) to the display 150 and outputs the audio data (oraudio signal or sound) to the audio output unit 160.

Furthermore, in case of a digital broadcast receiver provided with atleast two tuners, the digital broadcast receiver may be provided with anumber of demodulators corresponding to the number of tuners providedtherein. Also, the demodulators may each be separately provideddepending upon the ATSC type and the DVB type.

The network interface 130 receives data packets that are received from anetwork and also transmits data packets to the network. Morespecifically, the network interface 130 receives IP packets that deliverbroadcast data from a service provider through the network. Herein,broadcast data refer to contents, update messages notifying whether ornot contents have been updated, metadata, service information data,software codes, and so on. Also, service information may include serviceinformation on real-time broadcast services and service information oninternet services. Herein, internet services refer to services that canbe provided via the internet, such as CoD (Content's on Demand)services, YouTube services, information services including weatherforecasts, news, regional information, search services, and so on,entertainment services including games, karaoke services, and so on, andcommunication services including TV mailing services, TV SMS (ShortMessage Services), and so on. Accordingly, in the present invention,digital broadcast receivers include network TVs, web TVs, and broadbandTVs. Also, broadcast services may include broadcast services beingprovided via groundwave (or terrestrial), satellite, and cable and mayalso include internet services.

The controller 190 executes commands and performs operations associatedwith the electronic device 100. For example, by using a command searchedfrom the storage 180, the controller 190 may control the input andoutput of data between the components of the electronic device 100 andmay also control data reception and data processing. Herein, thecontroller 190 may be realized in the form of a single chip, multiplechips, or a plurality of electric assembly parts. For example, varioustypes of architecture such as an exclusive or embedded processor, asingle-purpose processor, a controller, an ASIC, and so on, may be usedfor the controller 190.

Along with an operating system, the controller 190 executes a computercode and performs operations of generating (or creating) and using data.An operating system is generally disclosed, and, therefore, a detaileddescription of the operating system will be omitted for simplicity. Forexample, the operating system may correspond to any one of a Windows OS,Unix, Linux, Palm OS, DOS, Android, and Macintosh, and so on. Theoperating system, another computer code, and data may exist within thestorage 180, which operates in connection to the controller 190.

The storage 180 generally provides a space for storing program codes anddata that are used by the electronic device 100. For example, thestorage 180 may be realized in the form of a Read-Only Memory (ROM), aRandom Access Memory (RAM), a hard disk drive, and so on. Program codesand data may exist in a detachable storage medium. And, when required,the program codes and data may be loaded or installed to the electronicdevice 100. Herein, the detachable storage medium may include a CD-ROM,a PC-CARD, a memory card, a floppy disk, an electro-magnetic tape, anetwork component, and so on.

The display 150 may operate in connected with the controller 190. Thedisplay 150 may correspond to a liquid crystal display (LCD) (e.g., anactive matrix LCD, a passive matrix LCD, and so on). In another example,the display 150 may also correspond to a monitor, such as a monochromedisplay, a color graphics adapter (CGA) display, an enhanced graphicsadapter (EGA) display, a variable graphics-array (VGA) display, a superVGA display, a cathode ray tube (CRT), and so on. The display 150 mayalso correspond to a plasma display or to a display that is realized byan electronic link.

The display 150 may display a graphic user interface (GUI) 153, whichprovides an interface that can be easily and conveniently used betweenthe user of the electronic device and the operating system, or betweenthe user of the electronic device and an application that is currentlybeing executed within the operating system. Herein, the GUI 153expresses programs, files, and operation options in the form of graphicimages. More specifically, a graphic image may include a window, afield, a dialog box, a menu, an icon, a button, a cursor, and a scrollbar. Such graphic images may be aligned in accordance with a pre-definedlayout or may be dynamically generated (or created) in order to assiston (or help) specific measures taken by the user of the electronicdevice. During the operation, in order to execute functions andoperations associated with various graphic images, the user may selectand activate a specific graphic image. For example, the user may selecta button for opening, closing, minimizing, or maximizing a window, orthe user may select an icon executing (or driving) a particular program.

The input device 170 may correspond to a touch screen positioned on thedisplay 150 or in front of the display 150. Herein, the touch screen maybe formed as a single body with the display 150, or the touch screen maybe provided as a separate component. In case the touch screen isprovided as a single body with the display 150, the touch screen mayalso be referred to as the display. As the touch screen is installed infront of the display 150, the user may directly manipulate (or maneuver)the GUI 153. For example, the user may simply put his (or her) finger onthe object that is to be controlled. In case of a touch pad, suchone-to-one (1:1) correspondence cannot be provided.

In case of using a touch pad, the touch pad is spaced apart from thedisplay 150 and positioned in a different plane. For example, thedisplay 150 is generally is positioned on a vertical plane, and a touchpad is generally positioned on a horizontal plane. This structure leadsto a less intuitive usage of the display 150 and the touch pad.Accordingly, in comparison with the usage of a touch screen, the usageof a touch pad is more difficult and inconvenient. In addition to beingconfigured of a touch screen, the input device 170 may also correspondto a multipoint input device.

The controller 190 may recognize (or detect) a gesture 171 being appliedto the input device 170, thereby being capable of controlling theelectronic device 100 based upon the detected gesture 171. Herein, agesture may be defined as a conventionalized interaction between theuser and the input device 170, wherein the gesture is mapped to at leastone or more particular computing operations. More specifically, thegesture 171 may be diversely performed by the hand of the user and, moreparticularly, by the movements of the fingers. As an alternative to thefinger movements, or in addition to the finger movements, a gesture maybe performed by using a stylus pen. Hereinafter, an item that produces(or causes) the gesture 171 may be referred to as an object.

The input device 170 receives the gesture 171, and the controller 190executes the commands for performing the operations associated with thegesture 171. Furthermore, the storage 180 may include a gestureoperation program 181 that may be a part of the operating system or apart of a separate application. The gesture operation program 181generally includes a series of commands notifying at least one or moresoftware agents of how to recognize the occurrence (or generation) of agesture 171, of what measure(s) to take with respect to the recognizedgesture 171 and/or in response to the recognized gesture 171.

When the user makes one or more gestures, the input device 170 deliversthe respective gesture information to the controller 190. Then, by usinga command language (or command) and, more particularly, by using thegesture operation program 181 from the storage 180, the controller 190interprets the gesture 171, thereby controlling different components ofthe electronic device 100, such as the storage 180, the display 150, theaudio output unit 160, the signal processor 140, the network interface130, and the input device 170. The gesture 171 may be identified ascommands performing the operations from the application stored in thestorage 180, correcting the GUI object shown (or displayed) on thedisplay 150, correcting the data stored in the storage 180, performingoperations of the signal processor 140, and so on. For example, suchcommands may be associated with zooming, panning, scrolling, turningpages, rotations, size adjustments, image channel changes, contentsreception, internet connection, and so on. Additionally, for example,the commands may also be associated with driving (or executing) aspecific program, opening a file or document, seeing a menu, selecting amenu or option, executing a command, logging-on (or signing-in) to aninternet site system, authorizing access of a certified individual to alimited area within the computer system, loading a user profileassociated with the alignment of icons within the wallpaper according tothe user's preference, and so on.

A wide variety of different gestures may be used. For example, a gesturemay include a single point gesture or a multipoint gesture, a static ordynamic gesture, a continuous or segmented gesture, and so on. Morespecifically, a single point gesture corresponds to a gesture performedby a single contact point. For example, the single point gesture isperformed by a single touch made by a finger or a palm of the user or bya stylus pen. A multipoint gesture corresponds to a gesture that can bemade of multiple points (or contact points). For example, the multipointgesture may be made of multiple touches, such as touches made by severalfingers, one or more fingers and the palm, one or more fingers and thestylus pen, multiple stylus pens, or by a combination of at least two ofthe above. A static gesture corresponds to a gesture that does notinclude any movement. Furthermore, a continuous gesture corresponds to agesture made of a single stroke, and a segmented gesture corresponds toa gesture consisting of a sequence of separate steps or strokes.

Generally, the contact between the object and the touch screen aplurality of different patterns. For example, within the touch screen,the single point gesture includes an object-down event followed by anobject-up event, which is performed at the same point or approximatepoint of the object-down event. Within the touch screen, the dynamicgesture includes an object-down event followed by at least oneobject-dragging event, which is then followed by an object-up event.

According to some embodiments of the present invention, a parameter fordescribing processes of a finger approaching the touch screen display,the finger contacting the touch screen display, and the finger movingaway from the touch screen display, is used. This parameter maycorrespond to at least one function among a distance between the fingerand the touch screen display, a pressure of the finger touching thetouch screen display, a contacting area between the finger and the touchscreen display, a voltage between the finger and the touch screendisplay, a capacitance between the finger and the touch screen display,and other physical parameters.

According to some embodiments of the present invention, depending uponthe size of a parameter (e.g., capacitance) between the finger and thetouch screen display, when this specific parameter exceeds a pre-decidedthreshold value, the object-down event occurs. And, while this specificparameter exceeds the pre-decided threshold value, when the position ofa cursor corresponding to the position of the finger moves from point Ato point B, the object-dragging event occurs.
